Although it takes a bit of extra care to train the weeping blue atlas cedar to its dramatic, drooping shape, the final result will be well worth the effort. Once weeping blue atlas cedar (Cedrus atlantica) is staked and trained, it will cascade like a silvery-blue waterfall, making it an evergreen that deserves a place of honor in the landscape. Weeping blue atlas cedar thrives in full sunlight and once established requires very little care. The tree won't tolerate hot, dry climates.
Plant the weeping blue atlas cedar where it will be exposed to full sunlight and where it will be protected from strong winds. Avoid planting the tree in areas where water tends to puddle five hours after a strong rain.
Stake the weeping blue atlas cedar immediately after planting. Drive a wooden or metal stake into the ground next to the tree. Tie the tree loosely to the stake with strips of soft fabric or strips of nylon stockings. Attach it to the stake every 4 to 6 inches as the weeping blue atlas grows. Stop staking the tree when it attains the desired height. The tree will grow horizontally in a flowing manner.
Keep the soil consistently moist for the first year. After that time, weeping blue atlas cedar is drought tolerant and requires little water, but it will benefit from an occasional watering during dry periods.
Feed weeping blue atlas cedar early each spring using a fertilizer formulated for evergreen trees and shrubs. Apply the fertilizer according to the label recommendations. Water immediately after fertilizing.
Prune weeping blue atlas cedar in early winter. Remove any dead, weak or scraggly branches, or branches that detract from the desired shape.
